Q7B18 contains:
- a fix for a suspend and resume hang, in new EC firmware 0.4.00,
which was easily reproducible with aggressive runin test timings,
- new bluetooth tests,
- new serial terminal feature, previously available out of the build;
this allows use of an XO as a serial terminal, without any operating
system, via the built-in UART or a USB serial adapter.
